IC Cards for easy transportation

For train and bus transport, most lines (including the local buses in Kashiwa) will accept the Suica or Pasmo IC Cards, which allow payment of fares by tapping a card reader. Either Suica or Pasmo cards can be purchased and recharged at most train stations and at the airport. Some express trains will require the purchase of an additional express fare ticket beyond the base fare, so simply tapping your IC card will not be sufficient. Local Tobu buses from Kashiwa or Kashiwanoha Campus Stations and from/to the airport also accept the IC cards. You simply need to tap the card readers when entering and exiting the bus. You can print a receipt of spent fares (e.g. for reimbursement of individual trips) at any machine where you can recharge the cards.

If you pay by coin, collect a paper slip when entering the bus which specifies your starting bus stop. Use the display at the front of the bus to determine your owed fare when you exit the bus. Payment is made at the front of the bus when exiting.

From the airport

There are two airports that service the Tokyo area, Narita airport and Haneda airport. We do not recommend to take a taxi from the airport to your hotel near Kashiwa campus or the symposium venue. From Haneda airport, taking a direct bus to Kashiwa-no-ha Campus station (about 1.5h trip) is most the convenient way. From Narita Airport, please use a train. You can check the bus timetables here:

or directly ask at the bus information desk at the airport. Please note that there may be buses only once an hour or less. Alternatively, you can take the subway/train through the city center and then Tsukuba express to Kashiwa-no-ha Campus station (operates more frequently and takes about the same time as the direct bus, but requires transferring at least two times):
